Safety note
Like any compost this is a living product and not sterile. Keep it damp while you handle it to limit dust, wear gloves, and wash your hands afterwards. Store the bag loosely closed somewhere cool; sealed airtight and warm, it goes anaerobic and starts to smell.

About this fertilizer
Castings from worms fed on vegetable waste and aged bedding, sieved to a fine crumble with the worms and cocoons screened out. It is dark, almost odourless and light in the hand.
The value here is biological rather than nutritional. Castings carry a dense population of soil microbes plus nutrients in a form plants take up easily, which is why a thin layer often does more for a struggling container plant than a stronger feed would. It is far too gentle to burn anything, so it is the safe choice for seedlings.
Recommended uses
- Top-dressing houseplants and container plants
- Mixing into seed-starting and potting mixes
- Giving transplants a gentle start without mineral feed
- Reviving pots that have gone tired and hard
How to apply it
Application instructions
Follow these in order. The rates below are the ones we test to, and going over them will not make anything grow faster.
Top-dress a pot
Scrape back the top half inch of old compost, spread castings a quarter to half an inch deep across the surface, and water gently. Repeat every 6 to 8 weeks through the growing season.
Blend into a mix
Use one part castings to four parts potting or seed compost, mixed thoroughly before filling trays or pots. More than that holds too much water for seedlings.
Use in the planting hole
A generous handful mixed into the soil at the bottom of a planting hole is enough for a vegetable transplant. It cannot scorch roots, so contact is not a problem.
